About Us

The diamond grading industry is populated by gemological laboratories that are virtually indistinguishable. In this “alphabet soup” of grading labs, diamonds are graded by hand and eye – an ultimately subjective assessment. While this continues to be standard practice for all laboratories, GSI has enhanced this process by adding advanced technology and intelligent software.

We at GSI have a vision: to create a modern, state-of-the-art diamond grading lab that takes advantage of the latest breakthroughs in diamond grading. To do this, we reengineered the diamond grading process and founded it on foolproof cutting-edge technology and automation. The result is diamonds that are graded to the highest standards.

How We Are Different

Proprietary software is at the heart of GSI’s diamond grading process. This state-of-the-art software reduces the chances of human error by automating the grading process.
